Abstract:
We present HI observations of the galaxies in the first list of the
Karachentsev catalog of previously unknown nearby dwarf galaxies
(Karachentseva & Karachentsev, 1998, Cat. J/A+AS/127/409). This
survey covers all known nearby galaxy groups within the Local Volume
(i.e. within 10Mpc) and their environment, that is about 25% of the
total sky. A total of 257 galaxies have been observed with a detection
rate of 60%. We searched a frequency band corresponding to
heliocentric radial velocities from -470km/s to ~+4000km/s.
Non-detections are either due to limited coverage in radial velocity,
confusion with Local HI (mainly in the velocity range -140km/s to
+20km/s), or lack of sensitivity for very weak emission. 25% of the
detected galaxies are located within the Local Volume. Those galaxies
are dwarf galaxies judged by their optical linear diameter
(1.4±0.2kpc on the average), their mean total HI mass
(4.6x107M☉), and their observed linewidths (39km/s).
